MARTIN JELALIAN, OF CRANSTON, RHODE ISLAND.

CUSHION-BUNTEB FOR SAILING VESSELS.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed January 4, 1916. Serial No. 70,156.

To all whom it may concern: 4

Be it known that I, MARTIN JELALIAN, a citizen of the United States, residing at the city of Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Cushion-Bunters for Sailing Vessels, of which the following is a specification.

This invention has for its object to provide a device adapted to be secured upon the bow of a sailing vessel and having a yieldable structure, tooperate in preventing damage through collision to the bow of the vessel.

The invention consists of the peculiar features of construction and combination of parts, as hereinafter described and claimed, reference being had to the accompanying two sheets of drawings wherein like characters indicate like parts.

Figure 1 is a side view of my improved device as applied to the bow of a sailing vessel, and illustrating the device as partly broken away and showing its interior yielding construction; Fig. 2 is a plan view of Fig. 1, showing the normal position of the working parts of the device; Fig. 3 is afront end view of the device; Fig. 4 is a similar view, showing the position the working parts assume after the vessel meets with an obstruction; Fig. 5 is a perspective view of the device, showing the relative position of parts as in Fig. 2; Fig. 6 is a similar view, showing a modified construction of the device; Fig. 7 is a plan view of the ar rangement of parts shown in Fig. 6, and, Fig. 8 is a similar view, showing the position the modified construction of parts assume through the yielding action of the dein carrying out my invention I employ a housing inclosing a yielding mechanism, to form a cushion bunter device.

Referring to Figs. 1 and 2, the housing comprises vertical plates which form side walls-4t, 4 that are hinged to the vessel near to the front of the bow thereof, as at points 2 and -3-; extension plates 5, 5- whose ends are pivotally connected to the front ends of said side walls, and also to a vertical head plate -6, as at points -22, 22-. The housing, formed by the plates as described, projects about an equal distance above and below the water line, and said housing, which is open at the top and bottom, incloses a series of sets of cushioning means, and as each set is constructed alike an explanation of one set of cushioning means will suffice. A bracket -8- is bolted to the sides of the bow part 1 of the vessel,and said bracket has an integral shaft 13 whose axis is in a plane centrally and longitudinally of the vessel. Over the shaft 13 is a slidable member 16 integral with the head plate 6 of the housing. The bracket 8 has also integral transverse shafts 9, 9- projecting from each side thereof at a point near to the bow of the vessel. The shafts 9, 9 pass loosely through openings formed in the side walls -1,4 of the housing, and each shaft -9 is curved around the bow of the vessel in order to permit the said walls to swing outwardly in the operation of the bunter device. Collars are formed on the bracket 8- at points surrounding its shafts 13 and -9, 9, as at -11 and 19--. An expanding coil spring -12 surrounds the shaft 13 and has its ends secured to the collar 11 and free end of the tubular member -16-. The shafts -9, 9- also have expanding coil springs -,18, 18- whose ends are secured to the collars 19, 19 and upon the inner face of the side walls 4, 4-. On the free ends of the shafts 9 are collars -17 to limit the outward movement of the walls -it. The head plate 6 of the housing, carries a pad 20- composed of a suitable yielding material, and said pad is secured in place by means of straps 23-, see Fig. 5. The tubular member -16 contains an expanding coil spring 17 whose ends are secured to the head plate 6 and end of the shaft 18-.,and said spring forms an auxiliary member designed to reduce the shock, by impact at the time of collision, and to assist the main spring 12 in the cushioning operation of the device. The members 18, surrounding the shafts -9, form pull-springs whose ends are attached to the collars -19 and walls -i, and said springs 18 are adapted to keep the housing to the normal closed m b rs r r a 1 7 1111' the modified'constructio'n shown in Figs. 6,i7 and 8-, the side walls''41-,of the r housing, are secured by bolts 13 to the i longitudinal yielding movement by this modified construction.

condition, as shown in Fig. 2. To assist the action of the pull-springs 18- the walls 4 have a series of sets of projecting rods 18 arranged in pairs, each pair of rods having a pull-spring connection therebetween. f V v -VVhen the hunter device meets in collision with an obstruction thelatter forces ,the

pad rearwardly and causes the housing to be brou 'ht'to an o J'ened condltlon as shown V. in Fig.4, and indicated by dottedlines 5in Fig. 3. Should the hunter receive impact against either wall+ or plate -5 in- 1 stead of against its pad 20 the side spring..18 then serves as a cushion memberfin lessening the shock upon the bow of the vesseL, Thus it is seen that the hinged r I or 'pivotal constructionof the housing permits flexibilityat all the points necessary to .afi'oi-d a; proper yielding, action of its spring sides of thebow of the vessel, and the front of this housing is constructed of one vplate to form'a head member '13 which is, substantially, a front convex shape, in plan view,and saidl member' has integral hangers -l9 193+ arranged to have a sliding fit uponthe top edges of "the walls 4, 4.

This modified construction of housing is;

provided longitudinally with a series of sets of cushioning, structures arranged in a similar manner as for the flexible housing already described, with the exception that the side shafts;+9 and their springs l8 are not employed' 'Inthis modified constructiona series of sets of springs 19" extendlongitudinally of the cushion members has oneend attached to a bar 15, fast in the wall 4, and its other end attached to the free end of a rod 12, which passes loosely'through an opening in said bar and, ismade fast to a support l2 integral of thehea d member 13 The side springs .,1 9 5serve toassist the central cushion members12: and 18 in affording the 7 It is obvious that by my constructionand arrangement of parts I provide a device that lessens to a degree the possibility of damage to the bows of sailing V vessels, and at the same time {a comparatively inexpensive structure to manufacture.
